UNITED STATES PATENT OFFICE.

GEORGE LEACH, OF NEW YORK, N. Y.

PULL-COCK.

Specification of Letters PatentrNo. 28,588, dated June 5, 1860.

To all lwhom 'it may concern:

Be it known that I, GEORGE LEAGH, of

vthe city and State of New York, have invented and made a certain newand useful Improvement in Pull-Cocks; and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the same, reference being had to the annexed drawing,making part of this specication, wherein- Figure l, is a side elevationof my said cock. Fig. 2 is an end view, and Fig. 3 is a cross section atthe barrel of the cock.

Similar marks of reference denote the same parts.

My said invention relates to cocks for use with pull pumps for beer, andale, and for soda water fountains or for tea or coffee urns, &c., wherea horizontal pipe unites with a vertical pipe or bib, and a barrel andornamental pull form the cock at the union of said pipes. In the cocksof this general character, difficulty has been experie enced in unitingthe handle to the plug of the cock so as to be strong and durable, andat the same time allow of the parts being easily detached for grindingin the plug of the cock.

The nature of my said invention consists in attaching the handle or pullto the plug of the cock by means of a follower acting on the spring thatdraws the conical plug'into place, so that the handle and pull is firmlyunited with the plug of the cock, and the appearance of the parts isuniform on both sides.

In the drawing a, is the pipe connected to the pump or source of supplyfor the liquid; b, is the bib or spout, and c, is the handle of thecock, these parts may be shaped and ornamented in any desired manner; Zis the plug of the cock turned and ound in as usual, but instead ofboring two holes at right angles and intersecting each other, I make useof a quarter circle cavity l, in the side of said plug to form the waterway as seen in Fig. 3. At one end of the plug CZ, I form a square 2,seen by dotted lines in Fig. 2, and the ornamental end or screw 3,connects the handle or pull c, at this point. The other end of thehandle or pull c, has a circular hole through the same as at 4, whichallows the aforesaid end to be placed over the square 2, after the plugis in place in the cock; and through said hole (-4) the spring 5, isentered, and the follower 6, placed within said hole 4, surrounds thesquare at this end of the plug and takes the screw 7 which acts tocompress the spring 5 by pressing on said follower, and a set screw 8,through the handle or pull at the eye or hole 4, enters a groove in thisfollower 6. It will now be evident that this follower 6, not onlyprevents the turning of the cock from loosening the screw 7, but it alsofills up the hole 4, and through the screw 8, affords a firm and durableconnection to the plug at this end so that the handle or pull acts atboth ends in turning said plug and thus prevents injury to the handle asoften occurs where rigidly connected only at one end of the plug.

The appearance of the cock is uniform and handsome and the action of thespring 5, in keeping the cock tight is not obstructed.

What I claim and desire to secure by Letters Patent is- The arrangementof the follower 6, spring 5, and screw 7 in connection with the handleor pull c, and` its screw 8, for the purposes and as set forth,

In witness whereof I have hereunto set my signature this twentieth dayof April GEORGE LEACH. Witnesses:
